For the past 2 day my I Pilot Link has not been staying linked. It will link up for a bit, then stop. Sometimes it has gone an hour or more without linking back up. On my navigation screen I'm getting a circle icon for boat placement, instead of the boat icon. I called Humminbird from the water and they suggested a software update and I know I need to do one, but that still doesn't explain (to me at least) why it worked fine one day and just started messing up the next day.

Is there a minimum speed for it to work? I haven't had any issues when trolling over .6 mph or so. It really started goofing when I slowed down to try spider rigging. At .3 mph I'm not sure it ever worked, even for a minute or two. It would blink on, but go right back off. I could try to reset factory default but I'm going to lose some data and weigh points because I forgot to put my SD card in. Is there a way to download that info to a card before doing a default reset?

I turned off and on both the Ulterra and the Helix multiple times thinking it would cause it to link back, but it didn't.
